Data Mining Analysis for Improving Decision-Making in Computer Management Information Systems

Xiaohong Dong,
Bing Xiang

Abstract: In this paper a decision tree-based data mining procedure for information systems is proposed to enhance the accuracy and efficiency of data mining. An enhanced C4.5 decision tree method based on cosine similarity is suggested to evaluate the information gain rate of characteristics and the information entropy of their values. When the information entropy variance among any two values for attributes is within the threshold range, the cosine similarity of the merging attribute values is determined, and the info… Show more
